Specification of Letters Patent.

Patented Aug. 8 1911.

Application filed May 27, 1907. Serial No. 375,762.

'To all whom it may concern:

Be it known that. I, EDGAR B. SYMoNs, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a certain new and useful Improvement in Stone- Crushers, of which the following is a specification.

My invention relates to stone crushers.

Figure 1 is a vertical section, Fig. 2 a cross section on the line 22 of Fig. 1-,- Fig. 3 a detail vertical section on the line 3-3 of Fig. 1, Fig. 4 a detail of the adjusting lever, Fig. 5 a plan view of the adjusting ring, Fig. 6 is a cross section on the line 6-'6 of Fig. 1 looking down, Fig. 7 is a cross section through a portion of the device of Fig. 1 on the line 77 of Fig. 6, Fig. 8 is a plan of the perforated washer on which the inner ring rests, Fig. 9 is a section of the same on the line 99 of Fig. 1, Fig. 10 is a section on the line 10-10 of Fig. 1, Fig. 11 is a section on line 1111 of Fig. 1, Fig. 12 is aplan View of the outer roller ca e, Fig. 13 is a side elevation of the same with parts broken away, Fig. 14. is a plan view of the inner roller cage, Fig. 15 is a side elevation of the cage with rollers removed.

Like parts are indicated by the same letter in all .the figures.

A is a base on which the body of the ma chine rests.

A is the hopper having removable crushing plates A A A is a ring which rests on the hopper and A? a yoke which connects the two sides of the ring with the central enlarged piece A in which the upper end of the tie rod A .is supported. The tie rod is reduced in cross section at A and is provided at the top with a nut A and a washer A. The tie rod is reduced again at the bottom at A to leave a shoulder whereby it is supported on the cen-' tral portion A of the base which is. connected by suitable arms A. at the base of the hopper. The tie rod is provided at its lower end with a nut A and washer A The tie rod has at each end the projecting screw-threaded portion to receive the nuts A and A".

A is a shield on top of the crown piece or middle portion associated with the upper ring and it is adapted to cover the upper end of the tie rod chamber and its associated parts and to serve as a means for lifting the an npwardly, projecting'ring like part D entire top of the crusher when desired. These several parts may be cast together or made in sections and connected together in any desired manner.

I B is the crusher head preferably shaped as shown with an outer crushing surface, and preferably provided with an inner cylindrical wearing surface B and a lower ring-like wearing surface B On this lower surface it rests on the adjusting ring C which is provided withan outer depending ring-like rim C provided on its outer surface with projections C and Midway of the ring there is another depending ringlike cam C having a succession of stepped $70 bearing surfaces. Theiadjusting ring rests upon the adjusting support which consists .of a lower part D bolted as indicated to a fixed portion of the base and provided with having a portion of uniform height D to bear upon the bottom part of the ring 0 and inner side of the depending ring portion 0 The part D is provided with another stepped surface D opposed to part of the cam C Toturn the adjusting ring C on the adjusting support a lever is provided. It comprises a handle E, a foot E a branch E and a hook E The foot is inserted in one or the other of the projections C on the adjusting ring and the hook engages one or the other of the projections C as the case may be. By operating the handle the ring will be turned in either direction to raise or lower the crushing head which rests upon it. Immediately surrounding the tie rod is the inner cage consisting of the rings F F, the rollers F F pivoted between them and the spacing rods F which with the rings form the cage. The cage rests upon a washer ring F which is perforated as at F F such perforations being connected together by grooves F F in both surfaces of the washer ring. Thus the oil in the tie rod chamber passes down through the Washer ring F into the oil chamber. The washer ring F isv preferably supported upon the fiber or protection washer FT which rests on the central portion ofthe base.

Immediately outside of the inner roller cage is the eccentric sleeve G which is reduced in size at its lower end and keyed at G to the gear wheel G The inneredge of this gear wheel rests on the outer edge of the washer ring F and the gear wheel supports on its sists of the rings H H, the rollers H pivoted therein and the tie rods Hwhich con nect the rings together. The lowenring H.- and the ends of the rollers lie within the oil" chamber, the upper portion of. which is formed by the interlocking adjusting ring and adjusting support. The'gear wheel Gr meshes with the driving pinion J on the shaft J 1 which passes through the long hearing J having the intermediate wearing sleeve J J 4 is an -oil cup 'on the top of the bearing connected by the passage-way J with the inner surface of the bearing.

J 6 is a collar at the outer end of the bearing surface of the shaft.

In the central ortion of the base an enlarged cavity K is formed and this cavity connected withthe cavity K inside the interlocking adjusting ring and adjusting support forms an oil chamber in which the gear wheels run and which also contains the lower portion of the tie rod and its associated parts. I I

K is an oil duct leading from the oil chamber 'to the oil tank K and K is a pipe leading thence to the oil pump K whence leads the pipe Kinto the screw plug K which passes intofthe side of the ring A. Thence leads an oil pipe K? to the annular chamber K about the upper end of the tie rod and above its upper shoulder, as shown in Fig. 1.- This produces an inclosed continuous oil compartment, including the tie rod chamber, the roller cage chambers, the oil chamber which contains the gears, thereservoir of the pump and the pipes. The whole comprises a circulatory oilcompartnient.

The oil pump is preferably driven by means of the belt L from the shaft J and this shaft is provided with the pulleys L and L the bearing L and the oil cup L for such bearing.

M is a chute which passes directly under the tie rod and under most of the annular passage-ways between the two crushing surfaces. It discharges at one side and just below the lower edge of the base or downwardly projecting portion of the hopper. This downwardly projecting portion has a hole M for the introduction of the adjusting lever.

I Having reference now to the upper part of Fig. 1 and the enlarged detail drawing of Fig. 7, and bearing in mind that the crusher head is adapted to move laterally and be adjusted Vertically, the structure for applying oil and protecting the oil compartment will be described. N is a sleeve about the tie rod and projecting upwardly into a recess in the crown portion At It is provided with vertical slots N on its inner face and by an outwardly and downwardly runnocdoae ning passage N The sleeveN is provided withv the lower downwardly projecting flange N through which the extension of the passage N? continues across the top of the eccentric sleeve to the outer roller cage. \Vhen the oil is introduced into the annular chamber about the upper'end of the tie rod,

it will pass down through these passageways out into the outer cage. Seated in the upper end of the crusher head is an annulus O with an enlarged central aperture so as to permit thehea-d and annulus to move laterally without striking the sides of the sleeve N. Another annulus surroundsthe sleeve and fits it closely and is provided with a series of upwardly projecting screw rods each provided with-a nut and each adapted to project into an aperture 0* in the crown A The sleeve N with its flange N holds the roller cages and the eccentric sleeve in proper and permanent relation to the other operative parts, while the crusher head. is free to be adjusted vertically and moved laterally." To keep the .chamber which contains these parts properly. closed is the oflice of the ring with its associated parts. The nuts 0 are loosened and the crusher head is then vertically adjusted whereupon the nuts are tightened against the lower side of the crown piece untilthe parts are brought into a position such as that illustrated in Fig. 7 where the oil compartment is closed. The oil passageway K is preferably placed in a channel Pin the lower part of the yoke A The ring A with its yoke or arms A and its central piece A may be called the crown.

It will be evident, of course,- that these parts may be greatly changed in general construction, size and shape and proportions without departing from the "spirit. of my invention.

The use and operation of my invention will be readily understood from the foregoing description and inspection of the drawings.

Some of the important features of the invention are the following: The oiling of all the operative parts is'efiected by means of a continuously acting oiling apparatus operating througha permanently closed oil compartment which contains all of the parts and which is kept permanently closed though some of the operative parts are adjusted to varying positions. The oil compartment, of course, does. not include the whole of the operative parts, but it does include either the operative parts or those surfaces which are to be oiled. The oiling. apparatus is also operative from the driving apparatus so that it is continuously operating during the operation of the machine.

In a stone crusher it is obvious, first, that on on incident to the operation of a crusher, second, that the wearing parts should be thoroughly and constantly oiled, and, third, that the oil supply and oil compartment should also -be thoroughly protected from the stone dust. The circulatory, variable, permanently closed and continuously operating oil supply with its various elements is one of the important features of my invention.

Another important feature of my invention is means for adjusting the size of the discharge opening. This is done by moving one or the other of the crushing surfaces which are inclined to each other so as by reason of such inclination to diminish the cross section of'the interval between them. In the form ofmystructure shown, I have shown the crushing head as adjustable. This involves-adjusting the crushing head vertically and the means which I have crusher head is maintaine for the case and shown are capable, of course, of variation so as to get any degree of adjustment. Thus the space between thetwo crushing surfaces can be made. of-any'desiredsize within prec -tel-mined limits. This is. accomplished by i e adjusting ringand support' whereby the v in its position. This adjustment takes place without in any manner affecting the position of the operativeparts. It isthe crusher head alone which rises-and falls and not any of the driving parts or the intermediate rollers or the eccentric sleeve. Another feature of this adjustable head,- however, is means for protecting and keeping permanently closed.
